Specification of Letters Patent.

Patented J an. 29, 1918.

Application led February 7, 1917. Serial N o. 147,215.

To all whom it may concern:

Be it known that I, FERRIS HADDAD, a citizen of the United States, residing at W'indber, in the county of Somerset and .State of Pennsylvania, have invented certain new and useful Improvements in Mufflers, of which the following is a specification, refer ence being had to the accompanying drawings.

This invention relates to certain improvements in mufllers and has relation more particularly to a device of this general character especially designed and adapted for use in connection with internal combustion engines of a type generally employed with motorcycles; and it is an object of the invention to provide a device of this general character with novel and improved means whereby the muffler may be readily cut out as may be required by the necessities of practice.

The invention consists in the details Vof construction and in the combination and arrangement of the several parts of myl improved muiiier whereby certain important .advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a View partly in elevation and partly in vertical section illustrating a muf iler provided with an embodiment of my invention; and f Fig. 2 is a sectional view taken substantially on the line 2-2 of Fig. l.

As disclosed in the accompanying` drawings, M denotes a muffler of a type generally employed in connection with motorcycles and provided at its forward end portion with the head H, said head being provided in one of its sides with a port l affording communication with the housing 2 arranged at one side of said head. In communication with the housing 2 through the forward end thereof are the pipes 3 leading from the exhausts of the cylinders of the motor (not shown) and which may be of any ordinary or preferred type. It is also to be understood that the number of pipes 3 depend upon the number of cylinders comprised in the motor.

The rear wall of the housing 2 is provided with an opening 4 substantially rectangular in form and which serves to afford communication direct with the atmosphere. The

opening 4C is adapted to be closed bythe has secured thereto a supplemental plate 7.

adapted to snugly fit within the openinget when the valve V is in closed position. It is also to be noted that the plate 6 is of such a width'as to extend beyond the outer side of the housing 2 so that the same may Vbe readily engaged by a foot to `fol-ce the valve V into closed position.

It is thought to be self-evident that when the valve V is closed the exhaust from the motor will be directed through the muliier but when the valve V is open the exhaust will pass directly to the atmosphere.

Underlying the bottom wall of the housing 2 is a spring member S formed of flat material and having its forward end p0rtion suitably anchored, as at 8, to the under` surface of the housing 2, and said spring member S extends a material distance to the rear of the rear wall of the housing 2.

At a point immediately adjacent the rear wall of the housing 2, the spring member S is offset upwardly, as indicated at 9, to afford a shoulder to overlie the lower or free end portion of the valve V, whereby said valve V may be effectively maintained in closed position. Upon depressing the free end portion of the spring member S the valve V is adapted to be automatically opened or swung upwardly through the medium of the retractile member 10 anchored at one end to the outwardly disposed lug 1l carried by the valve V and suitably secured at its opposite end to the upper wall of the housing 2.

The outer or free end portion of the spring member S is also adapted to be engaged by a foot so that-the same may be depressed sufliciently to permit the release of the valve V. The movement of the spring member S under pressure of a foot or otherwise is limited by the loop' member 1Q car- -ried by the bottom wall of the housing 2 and extending slightly beyond the rear wall of said housing and through which the spring member S is directed. The valve V is returned to closed position by a foot as` vinexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assem bled, and it will also be obvious that my in vention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish. to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying` out my invention in practice, except as hereinafter claimed.

I claim:

In combination with a muffler, a housing disposed at one side of the muffler at an end portion thereof and in communication therewith, said housing being provided with an induction opening, the face of the housing opposed to said induction opening being open', an upwardly swinging valve coacting with said open face and hingedly connected 'with the top of the housing, the intermediate portion of the valve snugly litting within the housing, a resilient member secured at one end to the bottom of the housing, said member being of such a length as to extend in advance of the open face of the housing, said resilient member being provided with a. shoulder overlyingl the free end portion of the valve for maintaining the valve in closed position, the portion of the resilient member in advance of the shoulder being of such a length as to permit the same to be readily engaged by a foot of a person, a loop extending from the bottom of the housing forwardly of the open face of the casing and through which the resilient member is directed, a portion of the resilient member in advance of the shoulder contacting with said loop for limiting the downward movement of the resilient member, and automatic means for opening the valve upon release of the shoulder of the resilient member from the valve upon depression of the free end portion of said resilient member.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
